Deep Purple ( B8 )

A second album, the creatively progressive Fireball, was issued in the summer of 1971, reaching number 1 on the UK Albums Chart.The title track "Fireball" was released as a single, as was "Strange Kind of Woman", not from the album but recorded during the same sessions (although it replaced "Demon's Eye" on the US version of the album). "Strange Kind of Woman" became their second UK Top 10 single, reaching number 8.

Within weeks of Fireball's release, the band were already performing songs planned for the next album. One song (which later became "Highway Star") was performed at the first gig of the Fireball tour, having been written on the bus to a show in Portsmouth, in answer to a journalist's question: "How do you go about writing songs?" Three months later, in December 1971, the band travelled to Switzerland to record Machine Head. The album was due to be recorded at the Montreux Casino, using the Rolling Stones Mobile Studio, but a fire during a Frank Zappa and the Mothers of Invention gig, caused by a man firing a flare gun into the ceiling, burned down the Casino. This incident famously inspired the song "Smoke on the Water". The album was later recorded in a corridor at the nearby empty Grand Hotel.

Continuing from where both previous albums left off, Machine Head became one of the band's most famous albums. It became the band's second number 1 album in the UK, while re-establishing Deep Purple in North America, hitting number 7 in the US and number 1 in Canada. It included tracks that became live classics, such as "Highway Star", "Space Truckin'", "Lazy" and "Smoke on the Water", for which Deep Purple is most famous. Deep Purple continued to tour and record at a rate that would be rare thirty years on; when Machine Head was recorded, the group had only been together three and a half years, yet the album was their sixth.
